Hi, Hercules team

I have a question about how to count error.

Whenever a single bit error or double bit error occurs, I want to count number of times a error occurred.

And I want to count single error and double error separately.

I couldn't find registers of error detection count.

Please let me know if TI has some guide or reference.

Hi SY,

The correctable errors i.e., single bit error count will be notified by EE_COR_ERR_CNT register

And count won't be applicable for uncorrectable errors i.e., double bit errors, And the first failing address of double bit error will be latched to the FUNC_ERR_ADD register.
